Biofinity XR (3 lenses)
Monthly Contact Lenses Biofinity XR
Biofinity XR are silicone hydrogel monthly lenses produced by CooperVision with the possibility of extended wear (when the lens is left in the eye during sleep). They are intended to correct high myopia and hyperopia, so they are produced with high plus and minus diopters. Biofinity contact lenses XR are designed for daily use but also are approved for extended wear. However, this method of use should be approved by an ophthalmologist.
Water content and oxygen permeability
The lens material Comfilcon A
combines high water content with good oxygen permeability. Biofinity XR
brings balance between the ratio of the water content and oxygen
Silicone is one of the hydrophobic (water-repellent) substances. One basic rule of hydrogel lenses is the more water the lens contains, the more oxygen permeates through. In the case of silicone hydrogel materials, the transmission of oxygen and metabolites is possible due to their free passage through microscopic channels in the lens.
Comfortable to wear
The aspheric front surface improves the optical properties of the lens and improves visual acuity in low-light conditions and allows correction of lower astigmatism and presbyopia. The lens has a rounded edge to increase comfort and prevent eye irritation. The design of the rear surface of the lens is constructed by using several curves. Thanks to this, the pressure made by the lens is equally distributed over the whole surface of the eye.
Technology AQUAFORM Comfort Science ™ uses a new silicone monomer, which provides more effective oxygen transmission through the lens. New technologies link the hydrophilic (water-binding) and silicone (water repellent) components in a way that creates a naturally wettable material. The water content is equally balanced throughout the entire volume of the contact lens.
Biofinity XR anti-deposits resistance
The material of the contact lenses contains no ions (electrically charged particles), so the lenses are resistant to the accumulation of protein and lipid deposits that are a common output of the tears and the external environment.
